The fixing supports are installed at regular intervals symmetrically along the boundary of a river. The connector is hinged between the fixing supports. The first tie bar is installed between the fixing supports. The contact balls are connected to the first tie bar. The second tie bar is installed on a first ring portion(119) and a second ring portion(129) formed on the fixing supports and the connector. The revolving balls are connected to the second tie bar. The spacer is installed between the revolving balls.
